Despite the fact that the Xbox One and PlayStation 4 have begun selling out at various retailers, indicating consumers' excitement over the next-gen, a research firm believes neither will match the sales success of their predecessors.

ABI Resarch expects combined Xbox One, PS4, and Wii U unit sales to reach 133 million within the first five years of launch -- down 5% from the 140 million unit sales for previous console editions.
"Without solid titles and first-party franchises, platforms will have a difficult time finding traction.

Streaming media is not enough when low-cost STBs are readily available," said Sam Rosen, practice director with ABI. "While we don't anticipate a drop-off in game console households, barring significant changes to less developed console markets in Asia and Latin America there isn't a great deal of growth opportunity beyond the current installed base."
